Those pesky cable companies would like you to think your sat signal goes completely out everytime it rains too.

You are correct, the army wouldn't use GPS if it wasn't all weather. GPS is an all weather technology, it just won't work in tunnels or inside all parking garages.
And I agree with you about the cable companies.
